One rainy night, Hammer sits brooding, alone, in a bar. But when he sees a desperate guy abandon his kid only to step outside and get blown away, Hammer's mood switches from bad to worse. By the time he reaches the man with the gun, the getaway driver has run him over to stop him talking. Hammer vows revenge on whoever's behind the crime. The trail of vengeance pits Hammer against his police friend Pat Chambers, the DA and his stooges and lands him in a world of trouble from gangsters, where he gives as good as he gets. And leads back to Marsha, a beautiful former Hollywood actress, who has more to offer Hammer than meets the eye.
